crcnnnrrn nx'rmemsm Application fled June 22, 1929. Serial No. 372,980..

This invention relates to cigarette extinguishers of the type wherein a perforated cup mounted above a water well is depressed to raise, water to the well for-extinguishing a '5} cigarette or cigar,-and the objects of the invention' are to provide improvements in such devices whereby they are cheaper to manufacture, easier to operate, and not so liable to leak. Other objects appear in the specifilOlcation to follow and in the drawings accompanying this application.

In the drawings Fig. 1 is a perspective view of my improved extinguisher as assembled complete with a butt and burnt match I receptacle on a common wall bracket.

' both being cylindrical sheet metal receptacles suspended on enlar ed shoulders through openings in the brac et.

The butt receptacle requires no description further than to say that it has a detachable funnel like portion3' :for guiding the waste matter to the receptacle and preventing its accidental dislodgment through jouncing of the vehicle in which the device is installed.

The extinguisher receptacle 4. is surmounted by a funnel-shaped cup 5 provided with a perforated bottom 6 and secured firmly to an upwardly arched soft rubber diaphragm 7 so that it may be depressed and the resihency of the diaphragm will always restore it to its elevated position} The diaphragm'is clamped at-its outer border against the upper edge of the receptacle by means of a flange ring 8 which may be either screwed or pushed tightly over the rim" of the receptacle, and the central portion of v the diaphragm is provided with a central opening so as not to cover the perforations in the bottom of thecup and is clamped to the cup by various means indicated in the modi- 59 .fications shown in Figs. 2 to 5.

and rep aced by a sponge 15 the action of In Fig. 2 the cup is guided for vertical movement b means of a dependent tube 9 loosely stra dling a guide pin 10 or rivet shank fixed to the bottom of the cup. The upper end of the tube 9 being outwardly flared and secured'as by solder or any other means to the bottom of the cup, and the diaphragm pinched between the bottom of the cup and a ferrule 11 tightly forced-over the tube 9. This ferrule may be soldered or an otherwise secured if desired, but a simple press fit will never come ofi unless desired to renew the dia hra'gm and when it may be forcibly pulled by engagement of a puller over a lower flange 12 provided for that purpose. I

In use water is kept in the receptable as shown at 13 and upon depressing the cup either with the finger or the cigarette the diaphragm forces the imprisoned air downward and raises the water in .tube 9 untilit appears in the cup so that the cigarette may through a passage in the shank of the rubber 0 cup and tube 9 into the extinguishing cup 5. In this construction the upper cup is also guided for vertical movement.

In Fi 4 the interior mechanism is omitted which when impregnated with water is selfevident.

In Fig. 5 the tube 9 is provided at its lower end with an enlarged plunger 16 slidably fitting within an auxiliary well- 17 pro- 00 vided with a minute aperture at 18 for ingress of water at the bottom. By depressing the cup 5 the water in auxiliary well 17 is forced upward into the cup 5 before it can escape from the small hole 18.

The design of Figs. 3 and 5 positively limit the amount of water forced into the upper cup.

-In any of the designs the receptacle is easily.

leaned by prying off, or unscrewing as the the outer clamping ring'S which case may be,

the upper edge clamps the diaphragm to of the receptacle.

While I prefer a soft rubber diaphragm it is manifest that other resilient material will work or even-a thin metal diaphragm, and I therefore claim:

1. A cigarette extinguisher comprising a well, a flexible diaphragm clamped to the top of the well, a cup carried by the diaphragm provided with a perforated bottom open to the underside of the diaphragm, and means within the Well adapted to force water from the well upward into the cup upon depressingthe same.

2. A cigarette extinguisher comprising a well, a flexible diaphragm clamped to the top of the well, a cup carried by the diaphragm provided with a perforated bottom open to the underside of the diaphragm, and means within the Well adapted to force water from the well upward into the cup upon depressing the same, and means for guiding the cup and diaphragm for vertical movement.

3. A cigarette extinguisher comprising a well, a flexible diaphragm clamped to the top of the well, a cup carried by the diaphragm provided with a perforated bottom open to the underside of the diaphragm, a dependent tube secured to the underside of the cup embracing the perforations, and means Within the well guiding the lower end of the tube for vertical movement.

4. A cigarette extinguisher comprising a well, a flexible diaphragm clamped to the top of the well, a cup carried by the diaphragm provided with a perforated bottom open to the underside of the diaphragm, a dependent tube secured to the underside of the cup embracing the perforations, and pumping means within the well guiding the lower end of the tube and for forcing water from the I well up the tube upon depressing the cup.

5. A cigarette extinguisher comprising a well, a flexible diaphragm clamped to the top ofthe well, a cup carried by the diaphragm prov ded with a perforated bottom open to the underside of the diaphragm, and means within the well adapted to force a measured uantity of water from the well upward into t e cup upon de ressi the same.
